Abstract

The present invention provides a seawater battery, which comprises an electrolyte, a cathode and an anode. The electrolyte is seawater, the cathode and the anode are separated from each other and respectively contacted with the electrolyte to enable an electrochemical reaction of the electrolyte respectively with the cathode and with the anode, so as to generate a potential difference between the cathode and the anode. In which, the anode contains a first material, and at least one of the anode and the cathode is selected for comprising a plurality of carbon nanotubes. Thus, the present invention employs the carbon nanotubes to fabricate the electrodes of the seawater battery for increasing the current density of the current formed by the potential difference, so as to effectively enhance the power supply performance of the seawater battery.

Description

technical field [0001] The invention relates to a seawater battery, in particular to a seawater battery whose anode contains carbon nanotube material. Background technique [0002] The structure of the battery is constantly being introduced with the progress of the times, such as common dry batteries, storage batteries, mercury batteries, air batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, solar cells, fuel cells, seawater batteries, etc., among which seawater The battery needs to be in contact with seawater to generate electricity when it is in use, and the electrodes do not contact the electrolyte (seawater) during normal storage. Compared with ordinary batteries that need to store electrodes and electrolytes together, it has better safety and is especially suitable for Applied to products related to the ocean and need to provide electricity. [0003] In Chinese Utility Model Patent Announcement No. CN2331087, a seawater battery...
